  • Apparatus and method for non-contact measurement of the edge sharpness of a knife
    Patent number: 5196800
    Abstract: Non-contact measurement of the sharpness of the cutting edge of a slitting or chopping knife is made repeatably placing a capacitance sensor probe symmetrically over the cutting edge at a predetermined distance (nominal offset) from the calibrated sharp edge of the knife and measuring the capacitance to derive a measurement that varies with knife wear (increasing knife edge radius). A novel sensor holder allowing for repeatable precision placement of the sensor.
